The Brachyopini (or Chrysogastrini) is a tribe of hoverflies. Unlike many members of this family these flies are generally darker and less colourful though some genera contain species with an attractive metallic lustre e.g. Chrysogaster . Some like Brachyopa are associated with sap runs where their larvae feed on decaying sap. Others are found in boggy areas where their often semiaquatic larvae feed on decaying organic matter. [1]
Subtribe: Brachyopina
Subtribe: Spheginina
Paragus is a genus of hoverflies.
Mallota is a widely distributed Holarctic genus of hoverfly, well known for their bee-like appearance.
Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.
Spilomyia is a genus of hoverflies. Many species in the genus show Batesian mimicry of wasp models, including black and yellow patterns and modified antenna shape.
Cheilosia is a genus of hoverfly. Most Cheilosia are black or largely un-coloured, lacking the bright colours and patterns of many hoverfly species. It is one of the most species diverse genera of hoverflies. The biology of many species is little understood, but where known, the larvae of Cheilosia species feed in the stems of plants or in fungi.
Criorhina is a genus of hoverflies. Medium to large sized species, black or greenish black, with or without light ground markings mimicking bumblebees. The head is much flattened and broader than the thorax. The antennae are situated upon a prominent conical frontal process, The face is moderately produced below the eyes, downward or forward, in profile. The eyes are bare. The abdomen is elliptical or very short oval. Larvae found in rot holes or decaying hardwoods
Chrysogaster is a genus of small hoverflies in the subfamily Eristalinae. They are dark or black with shiny colourful reflections and can often be seen visiting flowers in damp marshy areas where the aquatic larvae live. Species in the related genera Melanogaster, Orthonevra, Lejogaster and Riponnensia were formerly treated as members of Chrysogaster.
Brachyopa is a Holarctic genus of hoverflies whose grey and brown colouration is unusual for this family and these flies can easily be overlooked amongst members of other fly families. The larvae can be found under the bark of dead branches and trees in decaying sap.
Orthonevra is a genus of fly in the syrphidae family with at least 59 species identified so far. They are worldwide in distribution but concentrated in the Eastern North America and Europe.Orthonevra are commonly called Mucksuckers after the larvae which have been found in organic rich mud, i.e. muck. This genus belongs to the tribe Brachyopini that includes the prominent genera Melanogaster, Brachyopa, Neoascia and Sphegina. Orthonevra have black heads with blue to purple reflections. Many species have distinctive eye stripes. The antennae are somewhat elongate. The frons is wrinkled with silvery spots at sides of antennae. The thorax with small punctures dorsally and in several species the body is covered with scale-like pile. Wingd vein M1 curves away from the wing tip.(see images)
Pipiza is a genus Hoverflies, from the family Syrphidae, in the order Diptera. Most are dark hoverflies.
Trichopsomyia is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.
Brachypalpus is a genus of hoverflies, from the family Syrphidae, in the order Diptera. The head is triangular and produced well forwards and somewhat downwards. The thorax and abdomen with pile often rather long. The hind femur is swollen and with an obtuse spur apically and ventrally. The hind trochanters of male is spurred.
The larvae are of the rat-tailed type feeding on decaying sap under tree bark. Larvae live in decaying trees and logs. Larva and pupa have been described by Malloch.
Tropidia is a genus hoverflies, from the family Syrphidae, in the order Diptera.
The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.
The Spheginina is a subtribe of hoverflies.
The Brachyopina is a subtribe of hoverflies.
Total of 245 species either found or highly expected to be found in New York.
